A population has a growth rate of 12% per year. What is its doubling time?
1 point
- 6.25 years
- 5.75 years
- 5.25 years
- 6.00 years
Solution
To calculate the doubling time of a population with a growth rate of 12% per year, we can use the rule of 70. The rule of 70 is a way to estimate the time it takes for an investment or a population to double with a constant growth rate. The formula is:
Doubling time = 70 / growth rate
In this case, the growth rate is 12%. So, the calculation would be:
Doubling time = 70 / 12 = 5.83 years
So, the closest answer to 5.83 years is 5.75 years.
